I don't think I understand the economic model behind this being a chargeable item. Those that have ArtWorks don't need it; do those without AW really receive enough AW documents (that use transparency) to need to buy it?
Or is this a prelude to AWRender becoming a totally chargeable product? But that does not make sense (I think) because the idea behind a free renderer is that everyone can have it, thus fuelling demand for the (not-free) creator program - viz Acrobat, for example. After all, if people can't read documents you send them, isn't that a cue to change the way you send them, which *reduces* the demand for the creator program?
Still, kudos to Martin for providing the choice and I'll watch future developments with interest.
